A method for producing an object includes forming and laying N unit layers into which an object is divided, sequentially from a first layer to an Nth layer, using a resin material as a material, or using a resin material for implementing a step, to form the object, the method including performing a discharge treatment at either or both of a timing while forming a unit layer among the N unit layers, and a timing after forming the unit layer, but before starting forming a next unit layer among the N unit layers.

An apparatus for manufacturing a three-dimensional object by a layer-by-layer solidification of building material at the points corresponding to the cross-section of the object to be manufactured in a respective layer. The apparatus includes a process chamber in which the object is to be built up layer by layer by selectively solidifying layers of a building material in a build area, a gas supply device, and a recirculating air filter device, wherein the apparatus comprises a pressure stabilization device configured to keep the pressure in the process chamber substantially constant.

A method for controlling the direction of gas suctioning is carried out in a device (1) for producing a three-dimensional object (2) by selectively solidifying building material (13) layer by layer. The device (1) comprises an application device (12-14) for applying a layer of the building material (13) to a build area in a working plane (10), a solidifying device (20) for selectively solidifying the building material (13) in the applied layer, and at least two gas nozzles (40) which are arranged at the edge of the build area. The gas nozzles (40) are switchable into a function for suctioning gas from the device (1) and to a functionless state, and are switched depending on an operating state of the device (1).

In a three-dimensional modeling apparatus, diffusion of fumes generated around the modeling stage accompanying irradiation with an energy beam can be efficiently prevented. Three-dimensional modeling is performed by repeating scanning a modeling material arranged on a modeling stage with laser light to form a solidified layer. A cover is provided that locally surrounds an irradiation portion on the modeling material arranged on the modeling stage irradiated with the laser light, and suppresses diffusion of the fumes caused by irradiation with the laser light. In the cover, a stream of gas containing the fumes is regulated so as to cause the fumes to flow toward an upward portion inside the cover apart from the irradiated portion irradiated with the laser light.

The present invention relates to a device for generatively manufacturing a three-dimensional object (3), comprising: a frame (1) defining a building field (6) at an upper portion (2) thereof; a plate (12) which connects the frame (1) with a housing (100) of the device; a support (5) which is arranged in the frame (1) and vertically movable by a lift mechanics (4) at least below the building field (6); a radiation device (7) which generates an energetic beam (8, 8′) which is focused by a deflection means (9) to arbitrary points in the building field (6), so as to selectively sinter or melt a powdery material (11) which is present in the building field (6); a coater (10) for applying a layer of powdery material (11) onto the support (5) or a previously applied layer of the powdery material (11). A thermal insulation (13) is arranged between the frame (1) and the plate.

A system for removing residual powder from a three-dimensional (3D)-printed component integrally constructed with a build plate during an additive manufacturing (AM) process includes an end-effector, an enclosure, one or more transducers, and an electronic control unit (ECU). The end-effector includes a base surrounded by a perimeter flange, and includes a through-opening that receives the build plate. A perimeter clamp attaches and seal the enclosure to a perimeter flange of the end-effector such that the enclosure, the base, and the build plate collectively form a powder containment cavity. The transducers vibrate at a predetermined frequency or range thereof. The ECU transmits a vibration control signal to the transducers during a post-processing stage of the AM process to loosen and remove the residual powder from the component and collect the loosened powder within the powder containment cavity.
